275 tune and question about my trans.
I just got my S&B, Spartan, and FlowProw exhaust installed on my 08 F250. I have drove the 275 tune for 2 days now. My truck is NOT a Job1. I have done the "re-learn" process for the tranny, but the shifting from 1st to 2nd is very very hard and 2nd to
3rd is noticeably hard.....to the point that people riding with me ask "whats wrong with your truck shifting like that?" Its hard even when making a point to take it very easy driving. I dont "beat" on my truck, I dont race my truck, and I got the spartan mainly for the hopes of better fuel economy. I have read on here that the shifting is going to be more firm with the 275 tune, but I know this cant be good for the trans. I have also read on here that many others have 10,000-20,000-50,000 trouble free miles on their Spartan tuned truck running the 275 as a daily driver.
Does the shifting smooth out over time? Do I just go with it and hope that everything holds up? Am I just being overly paranoid?
